LASTlNG-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 436,851, dated September 23, 1890.

Application filed July 13, 1889. Serial No. 317,443. (No model.) t

To all whom t may concern:

Be it known that I, ISAAC N. FORBES, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and` useful Improvements in Lasting-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to certain improvements upon the lasting devices shown in my applications Serial Nos. 303,927, 312,484, and 313,616; and it consists in a carrier having a series of side-lasting fingers individually adjustable therein and readily removable as a whole from the lasting-machine to be replaced by a carrier and lasting-clamp adj usted to a different last.

It further consists in a removable lastingclamp carrier tube or frame adapted to receive individually adjustable lasting fingers and provided with a vertical shank adapted to be clamped in a suitable movable holder, whereby, together with great compactness, suiiicient length of the fingers maybe obtained for the desired elasticity or range of adjustment.

It further consists of a lasting-clamp holder of improved construction.

It further consists in certain parts and combinations thereof hereinafter more particularly set forth and claimed.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect.

In said drawings, Figure 1 is a vertical cross -sectional view, part full, of a holder having applied thereto a finger-carrier and series of individually-adjustable ingers. In this construction said carrier is shown as provided with a vertical stem or shank. Fig. 2 is a vertical sectional view, part full, of the carrier shown in Fig. 1, the fingers being removed. Fig. 3 is a horizontal sectional view, part full, of the same. Fig. 4 is a vertical transverse sectional view of the same. Fig. 5 is a view similar to Fig. 4, showing the two main portions of the carrier as separable upon a vertical plane and the shank or stem arranged horizontally and formed with or attached to the outermost of said main parts.

Fig. 16 is a vertical central section, at right angles to Fig. 14E, of a holder adapted for a finger-carrier, the stem of which is horizontal. Fig. 17 is a vertical transverse sectional view of a carrier and holder, part full, the carrier being of a modified form.

Referring to the drawings, B indicatesthe standard, secured to a suitable table (not shown) and carrying at its upper enda horizontal tubular bearing h3, in which is mounted a sliding sleeve-d, which carries at its inner end a hemispherical socket CZ, provided with a downward extension d6. In said socket is `mounted an inner bearing-piece g', having clamping devices adapted to receive and hold the shank f3 of the lasting-clamp, the lastingfingers or edges of which are adapted to operate upon the sides of the upper. v Side-actuating levers O are connected by links-c' with the sides of the slide-bearings d d and are adapted to draw said slides inward to cause the side-lasting clamps to perform their work. The hinge-bearings for connecting said links with the socket or bearing d are formed by enlarged portions d3 of the diametrically-opposite bolts d4, Figs. 13 and 16. The side levers O may be actuated by any suitable mech- .IOC

anismsuch, for inst-ance, as that fully del scribed and illustrated in my application No. 303,927, a description of which is not here necessary to an understanding of my invention.

The parts thus far referred to are preferably of the character described in my application No. 313,616, the bearing-piece g having a limited oscillation in its socket el', which is controlled by extension g, pin or screw C37, spring 97, and conical nut g1, and which is caused by the contact of the lower end of extension g6 as the side-lasting clamps move inward with a stop, (not shown,) with the result of automatically depressing the lasting-edges of said clamps, all as fully described and illustrated in my last-mentioned application, Serial No. 313,616. The inner socket-piece g has, however, according` to my present invention, certain features of modification and improvement. One of said features consists in its adaptation to receive a vertical stem or shank supporting the carrier of the lasting-clamp. (See Figs. l, 11, and 17.) This position of the stem gives the necessary distance between the side of the last and the center of. adjustment of the lasting devices, and at the same time enables the machine to be more compactly and economically constructed.

The carrier consists of a rod, frame, or tube I, formed in one or more parts and adapted to receive clamping-pieces t' and hold them loosely, one next to the other. The pieces t' have formed between them bearings adapt-ed to receive and fit the shanks of the separate and independently-adj ustable fingers f 14. The inner ends of the latter are shaped to lit the last and to operate properly in forcing the upper over it, and their shanks f15 are round, as shown, whereby they are adapted to be twisted into any desired position upon said shank as an axis between the bearing-pieces t and to be moved in or out. The bearingpieces being also adapted to oscillate to a certain extent within the tube I, the inner or operative ends of the lingers may be adjusted at different heights to t the instep or ball or other portion of the bottom edge of the last, and when thus in place the inward movement of a clamping-screw I forces a bearing-piece I? against the first clamping-piece 't' and presses the whole series, together with the intermediate finger-shanks, against the opposite end of said tube, thus firmly securing the whole series in their adj usted position. The fingers thus form whatI term a side clamp adapted for a certain contour of last.

Such a carrier and its clamping-pieces may be constructed in various ways. In Figs. l, 2, 3, and 4 the main portion of the tube or frame I, together with its inclosing ends, is formed by two trough-like pieces, which meet upon a horizontal plane and are pinned together, as shown at p p, and inclosed by bands p p. The interior of this tube is substan- --tially oval in cross-section, the greater dimension of which is the vertical one, and the clamping-pieces t' are of substantially similar shape, but aresmaller, so that they may be slightly moved vertically and rocked in the carrier to give a greater range of vertical adjustment to the lasting-fingers.

P is a spring interposed between one of the end-clamping pieces t' and the end wall of the carrier I. This spring is preferably held in place and protected from too much pressure by being mounted in a slot formed in abearing-piece p2. When the clamping-screw I is moved inward to secure the clamping-pieces, the piece next to the spring P compresses said spring iiush with the inner face of bearingpiece p2. Said clamping-piece then-comes in contact with said bearing-piece and all ofthe pieces t' are rigidly held between the part p2 and the bearing-piece I2 at the opposite end of the carrier. WVhen the clamping-screw I is relaxed, the springlP serves to exert sufficient pressure upon the clamping-pieces to keep them from dropping or being displaced from their proper position at or near the center of the tube, and also to maintain them in contact with the finger-shanks when the latter are inserted with a comparatively light pressure, which does not prevent the lingers and the clamping-pieces from being readily raised, lowered, or rocked. for the purposes of adjustment.

In Fig. 5 the carrier isdivided upon a vertical plane, such being the more convenient arrangement when, as in this figure, the supporting-stemf3 is horizontal. Such stem is in this figure shown as integral with the outermost of the parts of the tube I.

Y In Figs. 7, 8, 9, lO, and 11 the carrier-tube I is formed of a single piece, circular in crosssection, in which corresponding circular bearing-pieces t' fit neatly. In this case the carrier-tube is provided at each end with a clamping screw or plug I', between which the clamping-pieces are secured. Vith this form of tube the supporting-stem f3 may be either horizontal, as shown in Figs. 7, 8, 9, and 10, or it may be vertical, as shown in Fig. 11.

In Figs. l2, 13, 14, l5, and 17 there is shown a carrier, the main or tubular portion of which is formed in a single piece open from end to end upon its inner face. Each end of the tube is closed by a head-piece I4, held together and upon .the tube by longitudinal rods I5, which pass through the latter. Preferably these rods are in the form of elongated bolts, the heads and nuts t t7 of which engage the outer faces of the heads 14,. Through the open front of the carrier-tube the fingershanks are inserted at different heights, Fig. l5, corresponding with the average last-bottom contour, into the bearings formed for them between the clamping-pieces t. In this construction the clamping-piecesz'are perforated at each end, as shown, so as to loosely inclose the rods or bolts I5, Fig. 14:. Sufficient play is thus given to enable the clamping-pieces to be slightly rocked in the tube for purposes of adjustment,while at the same time any improper displacement of them is prevented. The bearing-screw I engages a screw-threaded aperture in one of the heads I4 and is adapted to force the clampingpieces against the opposite head.

InV Fig. 17 the main portion or tube of the lasting-nger carrier is made of somewhat greater diameter at its lower side than it is at its upper side, and the bearing-pieces, hinging neatly upon the upper of the bolts I5, are permitted at their bottom aslight inward and outward play for purposes of adjustment, their lower ends being provided with a perforation or recess sntliciently large that the -bearing-pieces-are not interfered with in their movement by the lower bolt I5. In this latter construction the supporting-stem f3 is vertical, vijhile in Figs. 12 to 16 it is horizontal. The stem f3 may be mounted in a universally-adj ust-able clamp or holder. Such a device adapted for a horizontal stem is fully described in my application Serial No. 313,616.

In Fig. l is shown a holder adapted to securely hold the carrier and permit it to be readily changed for one adj usted to`a different contour of last. In this construction the inner socket-piece g of the holder is provided with a recess adapted to receive the stem f3, With a pin gm, adapted to engage a longitudinal slot f1? in said stem to aid in guiding the latter and to insure its insertion in the proper position, with a bearing-piece g2, with a clampingscrew g5, adapted to force the latter piece against the stem f3 and secure it rigidly in place, and with diametrically-opposite hingebolts g4, by which it is connected with the outer socket piece. This inner socket piece is adapted to be automatically rocked in its outer socket d as the lasting-clamps are advanced, as already described.

In Figs. 7, 8, 9, 12, 13, 14, and 16 there is shown a substantially similar holder, with the exception that it is adapted for a horizontal carrier-stem, the aperture for the latter in piece g being horizontal and the clampingscrew g5 operating vertically.

In Fig. 17 the holder is adapted for a vertical stem, as already described; but the clamping-screw g5 is applied from the inner side of the holder through a suitable aperture in the outer socket d.

Perfect lubrication for the clamping-screw g5 is insured by means of an oil-hole adapted to conduct the lubricant to the outer face of the bearing-piece g2. When said screw is vertical the oil-hole passes vertically through it, Figs. 7, 8, 9, 13, 14, and 16. When the screw is horizontal said oil-hole leads through the part g to the plane of meeting of said screw and bearing-piece g2, Figs. l, 11, and 17. Similar provision is made for lubricating the screws I and bearing-pieces I2 by means of oil-hole t8.

While I have hereinafter claimed certain parts and combinations thereof as constituting my invention, it will be understood that I do not conne myself to the exact shapes or arrangements described, but that such claims extend as well to any parts or combinations thereof which are substantially the same, though (littering somewhat in shape, appearance, or operation from those herein illustrated and described.

I do not in this application claim, broadly, a carrier having a series oi' clamping-pieces and a series of independently-adjustable lasting ngers or clampsthe broader claims for such subject-matter being made in my application, Serial No. 312,484, led May 29, 1889; nor d0 I in this application claim, broadly, a cylindrical carrier or tube with or Without a shank and provided with a series ot' clampingpieces oscillatory therein, such cylindrical carrier or tube and clamping-pieces being the subject in part of my application, Serial No. 303,927, tiled March 19, 1889.
